Hey Capfo.
There are travel benefits with Emirates and Air Arabia as of now. (And FD obviously) its not quite ID90, you pay a little more and there are different "kinds" of stand by.
Yes, you can enjoy your 42 days of leave in different breaks, no less than 7 days in a row, if I remember correctly.
There is a new and fresh profit scheme available for pilots, but I dont have the details on it at hand.
As far as days off, it is my understanding that 9-11 is the norm. Closer to 9 seems more accurate. PBS is coming, dont know how that would change, if any.
Capfo, I strongly suggest you give this entire thread a good read. Sounds like you are on your early stages of research on FD. Its time consuming, but worth the read. It answers lots of questions, including the ones you are asking above.
Cheers!
